Comparing the two lamps, I would say:
# Both have a similar high brightness (OSRAM perhaps a touch more), you can replace both a 100W light bulb (60W the specified appear understated me).
# Light color Philips is slightly warmer than at OSRAM (thus the light output appears slightly less)
# In size (or compactness) clearly wins Philips
# OSRAM looks much more robust from (has great quality heatsink) and is much more difficult - but I see it as neither advantage or disadvantage
# Priced Philips is cheaper
So this LED comparison I can recommend the Philips perfectly!
Regarding the so-called saving lamps:
I would always prefer a one LED saving lamp as an LED emits a pleasant / flicker-free light. It may be that I am sensitive, but an energy-saving lamp in the living room while watching TV is not at all. The flicker upsets me full on ... electromagnetic pollution from all the ships as a saving lamp apart (inter
An LED does not have this disadvantage.
Mercury I have of course none in my living quarters have. Although I have to disagree with my previous reviewers "Sibi": The mercury is only released when the bulb breaks. Even as the mercury amounts are very low compared to the earlier clinical thermometers. And you should pay attention to the quality of the bulbs. Cheap lamps have a lot of mercury and also set many free, quality lamps have little mercury and this partly secured better.
